Immaculateness of the prophet in theoretical and practical wisdom

Guardianship is inner of prophesy and mission that are along with Imamate and caliphate. Moreover, recognition of Imams and prophet can be done along with recognition of guardianship. A person that is under guardianship of God has such a rank that he or she will see the world and the afterlife and will be innocent. The messenger of God (peace of Allah be upon him and his descendants) states in Quran
إِنَّ وَلِيِّيَ اللَّهُ الَّذِي نَزَّلَ الْكِتَابَ ۖ وَهُوَ يَتَوَلَّى الصَّالِحِينَ
For my Protector is Allah, Who revealed the Book (from time to time), and He will choose and befriend the righteous.
The messenger of God (peace of Allah be upon him and his descendants) is under guardianship of God and understands everything in a right way because foundation of the world is his guardian. Quran states
وَمَا نَتَنَزَّلُ إِلَّا بِأَمْرِ رَبِّكَ ۖ لَهُ مَا بَيْنَ أَيْدِينَا وَمَا خَلْفَنَا وَمَا بَيْنَ ذَٰلِكَ ۚ وَمَا كَانَ رَبُّكَ نَسِيًّا
(The angels say:) "We descend not but by command of thy Lord: to Him belongeth what is before us and what is behind us, and what is between: and thy Lord never doth forget.
Scientifically, the messenger of God is the best scientific verses of God and practically, it is the best practical verse of God. The messenger of God is the highest verse of God. Quran differentiates among believers, polytheists and righteous persons. Some Imams will achieve rank of righteous persons in the afterlife;
وَمَن يَرْغَبُ عَن مِّلَّةِ إِبْرَاهِيمَ إِلَّا مَن سَفِهَ نَفْسَهُ ۚ وَلَقَدِ اصْطَفَيْنَاهُ فِي الدُّنْيَا ۖ وَإِنَّهُ فِي الْآخِرَةِ لَمِنَ الصَّالِحِينَ
And who turns away from the religion of Abraham but such as debase their souls with folly? Him We chose and rendered pure in this world: And he will be in the Hereafter in the ranks of the Righteous.
Messenger of God is under guardianship of God directly;
إِنَّ وَلِيِّيَ اللَّهُ الَّذِي نَزَّلَ الْكِتَابَ ۖ وَهُوَ يَتَوَلَّى الصَّالِحِينَ
For my Protector is Allah, Who revealed the Book (from time to time), and He will choose and befriend the righteous.
If messenger of God is under guardianship of the messenger of God, his action and science will be innocent. Quran states
قُلْ إِنْ أَدْرِي أَقَرِيبٌ مَّا تُوعَدُونَ أَمْ يَجْعَلُ لَهُ رَبِّي أَمَدًا
Say: "I know not whether the (Punishment) which ye are promised is near, or whether my Lord will appoint for it a distant term''.
عَالِمُ الْغَيْبِ فَلَا يُظْهِرُ عَلَىٰ غَيْبِهِ أَحَدًا
He (alone) knows the Unseen, nor does He make any one acquainted with His Mysteries.
إِلَّا مَنِ ارْتَضَىٰ مِن رَّسُولٍ فَإِنَّهُ يَسْلُكُ مِن بَيْنِ يَدَيْهِ وَمِنْ خَلْفِهِ رَصَدًا
Except a messenger whom He has chosen: and then He makes a band of watchers march before him and behind him.
لِّيَعْلَمَ أَن قَدْ أَبْلَغُوا رِسَالَاتِ رَبِّهِمْ وَأَحَاطَ بِمَا لَدَيْهِمْ وَأَحْصَىٰ كُلَّ شَيْءٍ عَدَدًا
That He may know that they have (truly) brought and delivered the Messages of their Lord: and He surrounds (all the mysteries) that are with them, and takes account of every single thing.
Heart of the messenger of God is safe holy shrine of God;
نَزَلَ بِهِ الرُّوحُ الْأَمِينُ
. With it came down the spirit of Faith and Truth
عَلَىٰ قَلْبِكَ لِتَكُونَ مِنَ الْمُنذِرِينَ
.To thy heart and mind, that thou mayest admonish
وَإِنَّكَ لَتُلَقَّى الْقُرْآنَ مِن لَّدُنْ حَكِيمٍ عَلِيمٍ
As to thee, the Qur´an is bestowed upon thee from the presence of one who is wise and all-knowing.
Satan has no place in God;
فِي مَقْعَدِ صِدْقٍ عِندَ مَلِيكٍ مُّقْتَدِرٍ
. In an Assembly of Truth, in the Presence of a Sovereign Omnipotent
Rank of receiving divine messages is reliable messenger of divine messages;
نَزَلَ بِهِ الرُّوحُ الْأَمِينُ
With it came down the spirit of Faith and Truth.
Since the messenger of God is innocent, he achieves divine messages;
وَإِنَّكَ لَتُلَقَّى الْقُرْآنَ مِن لَّدُنْ حَكِيمٍ عَلِيمٍ
As to thee, the Qur´an is bestowed upon thee from the presence of one who is wise and all-knowing.
Quran states
سَنُقْرِئُكَ فَلَا تَنسَىٰ
By degrees shall We teach thee to declare (the Message), so thou shalt not forget.
خَالِدِينَ فِيهَا مَا دَامَتِ السَّمَاوَاتُ وَالْأَرْضُ إِلَّا مَا شَاءَ رَبُّكَ ۚ إِنَّ رَبَّكَ فَعَّالٌ لِّمَا يُرِيدُ
They will dwell therein for all the time that the heavens and the earth endure, except as thy Lord willeth: for thy Lord is the (sure) accomplisher of what He planneth.
وَعِندَهُ مَفَاتِحُ الْغَيْبِ لَا يَعْلَمُهَا إِلَّا هُوَ ۚ وَيَعْلَمُ مَا فِي الْبَرِّ وَالْبَحْرِ ۚ وَمَا تَسْقُطُ مِن وَرَقَةٍ إِلَّا يَعْلَمُهَا وَلَا حَبَّةٍ فِي ظُلُمَاتِ الْأَرْضِ وَلَا رَطْبٍ وَلَا يَابِسٍ إِلَّا فِي كِتَابٍ مُّبِينٍ
With Him are the keys of the unseen, the treasures that none knoweth but He. He knoweth whatever there is on the earth and in the sea. Not a leaf doth fall but with His knowledge: there is not a grain in the darkness (or depths) of the earth, nor anything fresh or dry (green or withered), but is (inscribed) in a record clear (to those who can read).
Whatever is point of view of the messenger of God (peace of Allah be upon him and his descendants) is considered as divine messages;
وَمَا يَنطِقُ عَنِ الْهَوَىٰ
Nor does he say (aught) of (his own) Desire.
إِنْ هُوَ إِلَّا وَحْيٌ يُوحَىٰ
It is no less than inspiration sent down to him.
Quran states
لَا تُحَرِّكْ بِهِ لِسَانَكَ لِتَعْجَلَ بِهِ
.Move not thy tongue concerning the (Qur´an) to make haste therewith
يَا أَيُّهَا النَّبِيُّ إِنَّا أَرْسَلْنَاكَ شَاهِدًا وَمُبَشِّرًا وَنَذِيرًا
O Prophet! Truly We have sent thee as a Witness, a Bearer of Glad Tidings, and Warner.
وَدَاعِيًا إِلَى اللَّهِ بِإِذْنِهِ وَسِرَاجًا مُّنِيرًا
And as one who invites to Allah´s (grace) by His leave, and as a lamp spreading light.
Messenger of God (peace of Allah be upon him and his descendants) states
اجود الاجواد الله جل جلاله انا احود ولد آدم
'' God is more merciful than other merciful persons''.
Guardianship appears prophesy, caliphate and Imamate. Quran states
وَمَا هُوَ عَلَى الْغَيْبِ بِضَنِينٍ
Neither doth he withhold grudgingly a knowledge of the Unseen.
Quran explains comprehensiveness of Quran and divine messages of the messenger of God (peace of Allah be upon him and his descendants)
هُوَ الَّذِي أَرْسَلَ رَسُولَهُ بِالْهُدَىٰ وَدِينِ الْحَقِّ لِيُظْهِرَهُ عَلَى الدِّينِ كُلِّهِ وَلَوْ كَرِهَ الْمُشْرِكُونَ
It is He Who hath sent His Messenger with guidance and the Religion of Truth, to proclaim it over all religion, even though the Pagans may detest (it).
إِلَّا تَنصُرُوهُ فَقَدْ نَصَرَهُ اللَّهُ إِذْ أَخْرَجَهُ الَّذِينَ كَفَرُوا ثَانِيَ اثْنَيْنِ إِذْ هُمَا فِي الْغَارِ إِذْ يَقُولُ لِصَاحِبِهِ لَا تَحْزَنْ إِنَّ اللَّهَ مَعَنَا ۖ فَأَنزَلَ اللَّهُ سَكِينَتَهُ عَلَيْهِ وَأَيَّدَهُ بِجُنُودٍ لَّمْ تَرَوْهَا وَجَعَلَ كَلِمَةَ الَّذِينَ كَفَرُوا السُّفْلَىٰ ۗ وَكَلِمَةُ اللَّهِ هِيَ الْعُلْيَا ۗ وَاللَّهُ عَزِيزٌ حَكِيمٌ
If ye help not (your leader), (it is no matter): for Allah did indeed help him, when the Unbelievers drove him out: he had no more than one companion; they two were in the cave, and he said to his companion, "Have no fear, for Allah is with us": then Allah sent down His peace upon him, and strengthened him with forces which ye saw not, and humbled to the depths the word of the Unbelievers. But the word of Allah is exalted to the heights: for Allah is Exalted in might, Wise.
كَالَّذِينَ مِن قَبْلِكُمْ كَانُوا أَشَدَّ مِنكُمْ قُوَّةً وَأَكْثَرَ أَمْوَالًا وَأَوْلَادًا فَاسْتَمْتَعُوا بِخَلَاقِهِمْ فَاسْتَمْتَعْتُم بِخَلَاقِكُمْ كَمَا اسْتَمْتَعَ الَّذِينَ مِن قَبْلِكُم بِخَلَاقِهِمْ وَخُضْتُمْ كَالَّذِي خَاضُوا ۚ أُولَٰئِكَ حَبِطَتْ أَعْمَالُهُمْ فِي الدُّنْيَا وَالْآخِرَةِ ۖ وَأُولَٰئِكَ هُمُ الْخَاسِرُونَ
As in the case of those before you: they were mightier than you in power, and more flourishing in wealth and children. They had their enjoyment of their portion: and ye have of yours, as did those before you; and ye indulge in idle talk as they did. They!- their work are fruitless in this world and in the Hereafter, and they will lose (all spiritual good).
يَحْلِفُونَ بِاللَّهِ مَا قَالُوا وَلَقَدْ قَالُوا كَلِمَةَ الْكُفْرِ وَكَفَرُوا بَعْدَ إِسْلَامِهِمْ وَهَمُّوا بِمَا لَمْ يَنَالُوا ۚ وَمَا نَقَمُوا إِلَّا أَنْ أَغْنَاهُمُ اللَّهُ وَرَسُولُهُ مِن فَضْلِهِ ۚ فَإِن يَتُوبُوا يَكُ خَيْرًا لَّهُمْ ۖ وَإِن يَتَوَلَّوْا يُعَذِّبْهُمُ اللَّهُ عَذَابًا أَلِيمًا فِي الدُّنْيَا وَالْآخِرَةِ ۚ وَمَا لَهُمْ فِي الْأَرْضِ مِن وَلِيٍّ وَلَا نَصِيرٍ
They swear by Allah that they said nothing (evil), but indeed they uttered blasphemy, and they did it after accepting Islam; and they meditated a plot which they were unable to carry out: this revenge of theirs was (their) only return for the bounty with which Allah and His Messenger had enriched them! If they repent, it will be best for them; but if they turn back (to their evil ways), Allah will punish them with a grievous penalty in this life and in the Hereafter: They shall have none on earth to protect or help them.
ا كَانَ لِأَهْلِ الْمَدِينَةِ وَمَنْ حَوْلَهُم مِّنَ الْأَعْرَابِ أَن يَتَخَلَّفُوا عَن رَّسُولِ اللَّهِ وَلَا يَرْغَبُوا بِأَنفُسِهِمْ عَن نَّفْسِهِ ۚ ذَٰلِكَ بِأَنَّهُمْ لَا يُصِيبُهُمْ ظَمَأٌ وَلَا نَصَبٌ وَلَا مَخْمَصَةٌ فِي سَبِيلِ اللَّهِ وَلَا يَطَئُونَ مَوْطِئًا يَغِيظُ الْكُفَّارَ وَلَا يَنَالُونَ مِنْ عَدُوٍّ نَّيْلًا إِلَّا كُتِبَ لَهُم بِهِ عَمَلٌ صَالِحٌ ۚ إِنَّ اللَّهَ لَا يُضِيعُ أَجْرَ الْمُحْسِنِينَ
It was not fitting for the people of Medina and the Bedouin Arabs of the neighbourhood, to refuse to follow Allah´s Messenger, nor to prefer their own lives to his: because nothing could they suffer or do, but was reckoned to their credit as a deed of righteousness,- whether they suffered thirst, or fatigue, or hunger, in the cause of Allah, or trod paths to raise the ire of the Unbelievers, or received any injury whatever from an enemy: for Allah suffereth not the reward to be lost of those who do good.
هُوَ الَّذِي أَرْسَلَ رَسُولَهُ بِالْهُدَىٰ وَدِينِ الْحَقِّ لِيُظْهِرَهُ عَلَى الدِّينِ كُلِّهِ وَلَوْ كَرِهَ الْمُشْرِكُونَ
It is He Who has sent His Messenger with Guidance and the Religion of Truth, that he may proclaim it over all religion, even though the Pagans may detest (it).
يَا أَيُّهَا الَّذِينَ آمَنُوا كُونُوا أَنصَارَ اللَّهِ كَمَا قَالَ عِيسَى ابْنُ مَرْيَمَ لِلْحَوَارِيِّينَ مَنْ أَنصَارِي إِلَى اللَّهِ ۖ قَالَ الْحَوَارِيُّونَ نَحْنُ أَنصَارُ اللَّهِ ۖ فَآمَنَت طَّائِفَةٌ مِّن بَنِي إِسْرَائِيلَ وَكَفَرَت طَّائِفَةٌ ۖ فَأَيَّدْنَا الَّذِينَ آمَنُوا عَلَىٰ عَدُوِّهِمْ فَأَصْبَحُوا ظَاهِرِينَ
O ye who believe! Be ye helpers of Allah: As said Jesus the son of Mary to the Disciples, "Who will be my helpers to (the work of) Allah?" Said the disciples, "We are Allah´s helpers!" then a portion of the Children of Israel believed, and a portion disbelieved: But We gave power to those who believed, against their enemies, and they became the ones that prevailed.
هُوَ الَّذِي أَرْسَلَ رَسُولَهُ بِالْهُدَىٰ وَدِينِ الْحَقِّ لِيُظْهِرَهُ عَلَى الدِّينِ كُلِّهِ ۚ وَكَفَىٰ بِاللَّهِ شَهِيدًا
It is He Who has sent His Messenger with Guidance and the Religion of Truth, to proclaim it over all religion: and enough is Allah for a Witness.
سَيَقُولُ لَكَ الْمُخَلَّفُونَ مِنَ الْأَعْرَابِ شَغَلَتْنَا أَمْوَالُنَا وَأَهْلُونَا فَاسْتَغْفِرْ لَنَا ۚ يَقُولُونَ بِأَلْسِنَتِهِم مَّا لَيْسَ فِي قُلُوبِهِمْ ۚ قُلْ فَمَن يَمْلِكُ لَكُم مِّنَ اللَّهِ شَيْئًا إِنْ أَرَادَ بِكُمْ ضَرًّا أَوْ أَرَادَ بِكُمْ نَفْعًا ۚ بَلْ كَانَ اللَّهُ بِمَا تَعْمَلُونَ خَبِيرًا
The desert Arabs who lagged behind will say to thee: "We were engaged in (looking after) our flocks and herds, and our families: do thou then ask forgiveness for us." They say with their tongues what is not in their hearts. Say: "Who then has any power at all (to intervene) on your behalf with Allah, if His Will is to give you some loss or to give you some profit? But Allah is well acquainted with all that ye do.
Quran states that sending divine messages to the prophet (peace of Allah be upon him and his descendants) is witness of his mission;
وَيَقُولُ الَّذِينَ كَفَرُوا لَسْتَ مُرْسَلًا ۚ قُلْ كَفَىٰ بِاللَّهِ شَهِيدًا بَيْنِي وَبَيْنَكُمْ وَمَنْ عِندَهُ عِلْمُ الْكِتَابِ
The Unbelievers say: "No messenger art thou." Say: "Enough for a witness between me and you is Allah, and such as have knowledge of the Book''.
